CHILDS CARRIAGE.

SPECIFICATION forming part of Letters PatentvNo. 224,976, dated February 24, 1880.

` Application filed December 8, 1879.

`To all whom it may Concern:

Be it known that l, JOHN B. W1GH'rMAN,of Brooklyn, in the county of Kingsand State of N ew York, have invented a new and useful Improvement in Ohildrens Garriages; and I do hereby declare that thefollowingis a full, clear, andexact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.

This invention is in the nature of an improvement in childrens carriages; and the invention consists in a childs carriage constructed with a reversible and pivoted body secured to horizontal sliding bars, to which the pushhandles are fixed, so that as the body is turned on its pivot the pivot and the center of gravity of the body are shifted and the leverage of the handles increased or diminished, as is more particularly hereinafter described.

In the accompanying sheet of drawings, Figure l represents a side elevation of my iniproved carriage with body reversed; Fig. 2, a longitudinal section of operating parts in line a; fr, Fig. 3, with body in ordinary position; Fig. 3, underside view of my carriage, with body reversed or facing push-handle 5 and Fig. 4, transverse section in line y y, Fig. 2.

Siinilarletters of reference indicate like parts in the several figures.`

A represents the body of a childs carriage, which may be of any desired size and form. To the Linder side of this body, or the iioor of the same, is centrally xed a pivot-pin, B. This pivot passes through the center of a spider, a, having four radial arms, b. The pivotpin, after passing through this spider, is bent ati-ight angles at c and d, forming thereby a crank, C.

To the side bars, e, of the runnin g-gear proper of my carriage are secured two parallel bars, j', which extend from one bar, c, to the other, spanning' them. These bars f have a space, g, between them, and into this space the crank C enters orprojects. Also, secured to the running-gear ot'l the carriage, and parallel with the bars e, are two guide-rods, 7L. These guiderods pass through the radial arms b` of the spider a. Also, to these radial arms of the spider are jirmly secured sliding bars D, these bars being parallel to and resting in contact with the inner surface of the parallel bars e. To the outer ends of these sliding bars D are tirmly fixed the push-handle bars 7c, and in any convenient manner, as to a brace, Z, is secured a bolt-rod, E, which passes beneath the spider a and into either the hole m or n, as the case may be, formed in a bearing-platas, fixed to the under side of the body A of the carriage. This bolt-rod has a spring, r, secured to it, so that the bolt-rod may, to some extent, act automatically, and be kept in place.

To the bars e are fixed the springs t and wheels and axles o and w, which are of the ordinary construction.

Now, my carriage being constructed substantially as l have described it, itis operated by simply turning the body A in either direction, (Whether back to the iront, or vice versa p) and as the body is turned on its pivot-pin B the crank C in the space g bears against the bars j', (on one when the body is turned in one direction, and on the other when it is turned in the contrary or other direction,) and as the body continues to turn this crank continues to bear against these bars, and by so doing it forces the sliding bars D outward or inward, as the case may be,depending upon the direction that the body A is turned and as these bars in this Way slide they are guided in their movement by the guide-rods h and the side bars, c, the radial arms b of the spider a sliding` on the rods, and the sliding bars D bearing against the sides of the bars e.

Vhen the body is fully moved or turned to the desired position the bolt-rod E. automatically, by tlie action of thespring r, enters into either one of the holes m or a in the bearingplate s, and holds the body iirmly in the required position until it is again required to shift the position of the body, when the boltrod is withdrawn and the body turned as bei IOO A is turned so as to face the handles 7c the back of the carriage is opposed to the sun or rain, shading and protecting the occupant therefrom 5 but when in this position the center of gravity ordinarily is so far back as to render the raising of the front Wheels by the handles,

' in order to pass a curb or other obstruction, a

matter of difficulty; but by my construction not only is the center of gravity thrown for- Ward under these circumstances, but the handles 7c are also thrust forward, giving room for the body to turn, and also increasing the le- Verage of the handles, so that with little 'efort upon them the carriage is tilted to raise the i'ront Wheels, so as to permit the Vehicle to readily pass any obstruction that may be opposed toit.

Having now described my invention, What -Iclaim as new, and desire to secure by Letters Patent, is`

1. A childs carriage constructed With a horizont-ally shifting` pivot, in combination With slide-bars, whereby the position of thel body of the carriage and its center of gravity may be changed by sliding the body horizontally on said bars, substantially as and for the purpose described.

2. In a childs carriage With a reversible body, extension slide-bars D, in combination with a crank, G, substantially as and for the purpose described.

3. In a childs carriage with a reversible body, the combination of slide-bars D, side bars, e, spider a, crank C, and parallel bars f, as and for the purpose described.

4. 1n a childs carriage vwith a reversible body, a crank, C, in combination with guiderods h, substantially as 'and for the purpose described.
